I visited Sacramento from the Bay Area recently, and the Jump bikes were a revelation. It seems to me that electric-assist bikes are an easier sell safety-wise than scooters (bike lanes often already exist). I’m from Austin Tx and I really hope that the electric assist bikes see widespread adoption there, especially given the horrific traffic and historical resistance to public transit there (biking in the summer there is a hard sell, and it seems to me that electric assist could reduce the number of cars on the road)
AND I could see electric assist leading to cyclists making full stops at stop signs (since the need for momentum hacking is not so great). Based on what I've read here, that would go a long way towards drivers and cyclists getting along better.
